The DANCe (Dynamical Analysis of Nearby ClustErs) project aims at deriving a comprehensive census of the stellar and substellar content of a number of nearby (<1 kpc) young (<500 Myr) associations. Members are identified based on their kinematics properties, ensuring little contamination from background and foreground sources. We show how robust individual proper motions can be computed with a precision better than 1 mas/yr by combining thousands of wide-field images downloaded from public archives and covering more than a decade of observations.
